  • Electrical characteristics inspection tool
    Patent number: 11402408
    Abstract: An electrical characteristics inspection tool capable of inspecting electrical characteristics even when an oxide film is formed on pads or bumps formed at a fine pitch. The electrical characteristics inspection tool includes: a flexible sheet; a through electrode having a recess that is recessed from one surface of the flexible sheet; and a conductive elastomer disposed in the recess of the through electrode. Electrical characteristics can be inspected even when an oxide film is formed on pads or bumps of an inspection object by bringing the conductive elastomer into contact with the pads or bumps and bringing a probe into contact with the through electrode since the conductive particles in the conductive elastomer break through the oxide film.
    Type: Grant
